Looks great to me, especially the interior. Some other
designers should be forced to look at how to integrate the tech into the dash with a fresh look, instead of the sometimes deal killing ipad crazy glued to the dash look. Or they could look at my Elantra Sport or the new VW Jetta GLI for 'ideas'.

I'd have to see the daytime running light 'streaks' in person to see if its a good addition. To me its not good that its 2" longer than the existing Sonata, making it one of the longest mid size cars.
Now the all important question is engine and transmission choices. It needs the yet-to-be launched Hyundai 2.5 turbo as the optional engine (or a strong V6, not going to happen).
